HORSE-1POWEFL SPECIFICATION forming part oi Letters Patent No. 309,608, dated December 23, 1884.

Applica ion lili-l October *27, lrSl.

Zo (LM whom, it may concern:

Be it known that I, Lnwis H. Davis, of Davenport, iu the county of Scott and State of Iowa, have invented certain new and useful Improvements in Horse-Powers, of which the following isa description, reference being had to the accompanying drawings, in which- Figure l is a perspective view ofsaidhorsepower, showing the sweeps removed and loaded for transportation. Fig. 2 is a plan view ofthe frame of said power with the master-wheel removed and showing the means i'or bracing said power when in use. Fig. ."5 isan end view of the frame showing one oi' the bevel-whcels for driving the line-shaft, the arch supporting the saine, and the friction-rollers for sustaining the master-wheel. Fig. et is a transverse vertical sectional view ofthe frame, taken on the line t 4, Fig. 2, as viewed in the direction of the arrow there shown; and Fig. 5 is a central longitudinal vertical sectional view of said frame as shown in said lastnained figure.

f Likeletters of reference indicate like parts in the different iigures.

The object of my inventionis to overcome many of the objections to horse-powers heretofore in use, and to provide aportablepower which shall be light and compact in form, cheap and du able in construction, which may be securely ,and easily bracedfor use while standing upon the carriage upon which the saine is transported from place to place, and the construction of which may be such as to permit said carriage to be turned within a very limited space.

My invention relates, particularly, to the manner of constructing the bed or framework of said'power, whereby I ain enabled to ae complish said results, all of which will bc hereinai'ter more fully described, and definitely pointed out in the claims.

In the drawings, A represents the bed or main supporting-frame' l'or said power, the

' saine being made oi' cast-iron, and constructed as more clearly shown in Fig. 2, being widcned at or near the ends, and provided with a central longitudinal depression, a, Fig. et, in which the lineshaft a is located in bearings cz fr. Step-boxes a" c, Fig. 5, are bolted or otherwise rigidly secured to said bed A at or near the respective ends, forming bearings (No model.)

for the vertical shafts b b ot' the bevelwheels B B, which mesh into pinions c* at, Fig. 5, upon the line-shaft n'. rackets er c5, secured rigidly to said bedplate, as shown, serve as supports for the friction-rollers a c, which bear upon the periphery oi" the wheels B B and hold them in mesh. rigidly to the wheels B B, serve to engage the usual annular master-wheel, C, Fig. 1, andare propelled thereby.

ln order to i'orin bearings for the top of the shafts b I), the bedsplate A is made somewhat wider, as stated, at or near the ends opposite the shafts b b than the diameter ofthe wheels B B, and is provided with upward extensions al ci. Fig. 3, to which is secured by means of the bolts dd arches D D, Figs. Zand 3, through which the shafts b b project, as shown. The arches D D are connected with each other by means of a cross-bar, E, Figs. 2 and 5, the extremities of which are bolted to suitable flanges, c c, Fig. 5, by bolts c c'.

Con centric with the master-wheel,and forming a pivotal bearing therefonis a pin or pivot, ci, Figs. 2, Lt, and 5, secured to the middle ot' said bridge E, and Aprojecting upward there from, so that the usual plate, F, Fig. l, connccted `to the radial cross-hars of the masterwheel (l may rest thereon. A bracket or central support, G, Figs. Lt and 5, serves to relenforce said bridge E, and to distribute the weight between that and the bed A. Plates d ddd, secured bybolts d d (l d, to the opposite extremities of the arches D D, forni supports or bearings for the 'friction-rollers d d2 d2 d?, which in turn tend to support the master-wheel (l. The bed-plate A is supported upon trucks il in any well-known manner, by being preferabl y elevated to nearly the height of the wheels, substantially as shown, Fig. l, to permit the front wheels to turn to the fullest extent desired, which it is obvious may be readily accomplished for the reason that the wider portions of said bed-plate are directly between the wheels, while the middle portion is quite narrow.

shaft cin front `of said power, as shown in Fig. l, so that the connecting portion as, Figs. l and 5, may extend toward the thr'asher, and may be brought readily into alignment there with as the power is driven into position. XVhen so placed, the power maybe thoroughly l. prefer to extend the` line- Pinions b b', secured IOO and securely braced as follows: Bars J J, havl. In a horse-power, the combination of the ing one end placed upon the ground, and the other against the blocks or projections a7 ai, beneath the plates d d, are secured in position, respectively, upon opposite sides of said power, and at opposite ends thereof, by means of the stakes jj', (of which there are four, two being shown in Fig. 3,) the lower or grounded end of each of said bars abutting against one of saidstakes, and being connected with the opposite end of said power by means of rods J J which are hooked into holes jZ j?, Fig. 2, inthe lugs upon the extremities of the plate A.

It is obvious that the bars J J act as braces,

and receive a pushing strain, while the rods J J sustain atensional strain, the lateral movement of the lower ends,respectively,of the bars J J being prevented by means of the stakes j.

For the purpose of supporting the powersweeps or levers while in transit, I provide racks K K, Fig. l, each of which is provided with a downwardly-projecting rod, k,which is inserted into suitable holes in projections k it,

one of which is shown in said ligure upon opposite sides of the master-wheel C. This is a great advantage, as it saves loading said detachalole parts upon afseparate carriage for conveyance. The tongue is detachably secured to the front axle in the usual manner by means of hooks and eyebolts.

. It is apparent that by adopting this form of' construction the entire power, except the sweeps, may loe made of iron, thus producing a frame that will not warp or twist from the action of the Weather, and thus interfere with the working mechanism, but is practically indestructible.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

bed A,constructed, as shown,with lateral projections or extensions at the respective ends to form supports for the arches B B, and frictionrollers d, line-shaft a', with beveled pinions thereon, bevel-wheels B B, arches D D, connecting-bridge E, bracket'G, and pivot ewith the usual master-wheel, substantially as and for the purposes set forth.

2. In a horse-power, the combination of the bed A, constructed, as shown,with lateral projec'tions or extensions at the respective ends to form supports for the arches B B, and friction-rollers d2, line-shaft a', with beveled pinions thereon, a front extension upon said bed to support the bearing for the extended portion yof the line-shaft, bevel-wheels B B, blocks or projections al, arches D D, connectingbridge E, bracket G, and pivot e2, with the usual master-wheel, substantially as and for the purposes set forth.

3. A horse-power consisting of the bed A, line-shaft a, pinions a4 a, in combination with bevel-Wheels B B, pinions b b', master-wheel C, bars J J, and rods J J, said bed being constructed, as shown, with lateral extensions at either end to form supports for the arches D D, and friction-rollers d2, and provided with perforated lugsjzjz, whereby said power may be turned within a minimum of space, or braced in position for use without removal from the carriage, substantially as and for the purposes set forth.
